Which indicators are monitored by avionics health monitoring to assess system health?

• A. Abnormal voltages, temperatures, currents, and fault statuses.
• B. Only altitude readings.
• C. Only airspeed.
• D. Only structural data.

Answer: (A)

Monitoring avionics health focuses on the electrical and thermal state of the system and on explicit fault indicators. Abnormal voltages can reveal power supply or distribution problems, abnormal temperatures point to overheating or cooling failures, and abnormal currents can indicate short circuits or excessive draw from components. Fault statuses provide direct flags from modules about their readiness, faults, or degraded health. Together, these indicators give a real-time view of whether the avionics are operating within safe electrical and thermal envelopes and help flag issues before they impact safety. Altitude readings, airspeed, and structural data describe the aircraft’s flight state or airframe condition, not the health of the electronic systems themselves. They’re monitored for flight operations, not to assess avionics health, which is why the combination of abnormal voltages, temperatures, currents, and fault statuses is the appropriate set to monitor.
